No, that is a hold over from the MM statblock. I guess teh marilith could use it to pop into melee range from a hidden position. It makes some sense if the PCs are already facing a group of demons and then the marilith teleports in and changes the whole battle.You did. I guess it's okay. But I don't see the marilith using teleport before it's done for.
Yep, perhaps to harsh, I'll think about it.No, I read it right, then. So losing 5-6 reactions to get rid of some effect. Tough choice.
